[PATCH v1 2/2] erofs-utils: Set mkfs default blocksize based on current platform

[Sandeep Dhavale]

Set mkfs default blocksize to current platform pagesize.
This means mkfs with default options will work on current
platform. If we are building image for a platform for a different
blocksize, we can override default with -b option up to
EROFS_MAX_BLOCK_SIZE.
